Decuana hispida Dumitrescu and Georgescu, 1987: 92 , pl. 2, 3 (two males, one female syntypes from Rancho Grande [probably Parque Nacional Henri Pittier, Aragua], Venezuela, XI.11.1982, T. Orguidan and V. Decu col., in “Grigore Antipa” National Museum of Natural History, Bucharest, not available).

DIAGNOSIS: Males resemble those of N. boibumba in having abdominal anterior denticles and lacking carapace spikes, but differ by the longer pedicel, inserted obliquely in relation to the postepigastric scutum (fig. 203). Females differ from those of N. furtivus and N. keyserlingi by the smooth carapace, epigynal atrium strongly rebordered anteriorly and median element with long accessory prongs (figs. 216, 217). Females may be further distinguished by the presence of two prolateral spines on femur I (fig. 212), contrasting with those of N. furtivus , with one and with those of all remaining species, devoid of spines.

MALE (PBI_OON 40608, MNRJ): Total length 2.61. Carapace orange-brown, posterolateral surface without spikes, with a pair of raised blunt tubercles near the posterior margin (fig. 203), surface of elevated portion of pars cephalica smooth, sides finely reticulate, lateral margin with small, inconspicuous tubercles. Clypeus margin unmodified, straight in frontal view. Eyes: ALE separated by less than their radius. Sternum as long as wide, pale orange, median concavity absent, microsculpture absent, furrows shallow, setae evenly scattered, originating from small tubercles. Chelicerae, endites, and labium pale orange. Book lung covers large, ovoid. Pedicel tube medium sized. Dorsal scutum orange-brown, surface of middle and sides reticulate, anterior half with projecting denticles. Postepigastric scutum orange-brown. Legs yellow. Spine formula: tibia I v2-4-2, metatarsus I v2-2-2; tibia II v2-4-2, metatarsus II v2-2-2. Genitalia: sperm pore situated between anterior and posterior spiracles. Palp proximal segments yellow, cymbium and bulb white. Embolus with well-developed apical projection, without prolateral prong or prolateral prong, with a prolateral basal notch (figs. 209–211).

FEMALE (PBI_OON 40626): Total length 2.84. Dorsal scutum anterior half without projecting denticles. Carapace posterior surface with additional retrolateral protruded tubercle. Leg spination femora: I v0-0-2; tibiae: I, II v4-4-2; metatarsi: I, II v2-2-2. Epigynal median element large, curved, with conspicuous accessory prongs (figs. 216, 217).

DISTRIBUTION: Known from the type locality and from Lara Department , Venezuela (map 2) .
